Hi There,
I have a Sternglas Zirkel at 40mm which is too large for me. One thing with their watches that you have to take note is that they wear really large because of the really thin bezel.
Other than that the design is awesome to me and the Miyota movement that they use is a workhorse though as per most Miyota's, the rotor is a little noisy.
I actually really like the Milanese bracelet that came with it and have been using it on other watches as well.
